MUNROE 1 1National Systematics Laboratory, NMFS/NOAA, Smithsonian Institution, Post Office Box 37012, NHB, WC 57, MRC–153, Washing- ton, DC 20013–7012,U.S.A. Email: [email protected] Abstract Since its description, Azyygopus Norman, 1926 was considered by subsequent authors to be a monotypic genus in the Or- der Pleuronectiformes comprised only of A. pinnifasciatus Norman, 1926, known from deep waters (90–900 m, usually 200–600 m) off the southern and southeastern coasts of Australia. In 1961, a subspecies, A. pinnifasciatus flemingi Niels- en, was described based on three specimens collected at 610 m in the Tasman Sea off the South Island, New Zealand. From its description to contemporary literature evaluating its status, recognition of A. p. flemingi as a distinct taxon has been rejected by all but two studies reporting on Azygopus from New Zealand waters. Until the late 20th century, specimens of Azygopus had been rarely collected off New Zealand and little was known about these fishes. Over the past 25 years, col- lecting by scientific expeditions and expanding deep-sea fisheries have captured over 195 specimens of Azygopus from a variety of deep-sea locations around New Zealand. Recently-captured specimens of Azygopus collected around New Zea- land and deposited in fish collections have been identified as either A. pinnifasciatus Norman or A. flemingi Nielsen, sug- gesting the possibility that two species of Azygopus occur in New Zealand waters. This study examined the holotype, a paratype, and 25 non-type specimens of A. pinnifasciatus collected off Australia, and the most comprehensive series of specimens of Azygopus collected from New Zealand waters. These specimens included the holotype and two paratypes of A. p. flemingi and 191 other specimens collected from throughout the entire depth range (153–942 m) and representing wide coverage of geographic areas around New Zealand where Azygopus have been collected. Comparisons of these spec- imens indicate that a second species, A. flemingi Nielsen, should be recognized in the genus Azygopus, and that this species is the only member of this genus occurring in New Zealand waters. Azygopus flemingi is readily distinguished from A. pinnifasciatus by conspicuous differences in ocular- and blind-side color patterns, in numbers of ocular-side pelvic-fin rays, total vertebrae, lateral-line scales, and gillrakers on the first gill arch, morphology of blind-side scales and squama- tion patterns, length of blind-side pectoral fins, presence/absence of scales between upper jaw and ventral margin of lower eye, and pigment patterns on dorsal and anal fins of adults. Adult A. flemingi and A. pinnifasciatus are sexually dimorphic in several features. Data on maximum size and size at maturity, and depth of occurrence are summarized for A. flemingi. Key words: rhombosoleid flatfish; taxonomy; New Zealand endemic fishes; deep-sea flatfish; species re-description; squamation; scale morphology; Azygopus pinnifasciatus; sexual dimorphism Introduction Azyygopus Norman, 1926 has been considered by most subsequent authors (Norman 1934; Sakamoto 1984; Evseenko 2004; Gomon 2008; Eschmeyer & Fricke 2012) to be a monotypic genus in the Order Pleuronectiformes comprising only A. pinnifasciatus Norman, 1926. Azygopus pinnifasciatus had been reported only from deep-water locations (90–900 m, usually 200–600 m) off the southern and southeastern coasts of Australia (Norman, 1926; Norman 1934) until Moreland’s (1957) report of deepwater flatfishes, identified as A. pinnifasciatus, taken in 1954 off the Chatham Islands, New Zealand. Though Moreland’s report (based on an unknown number of specimens) represents the first published record for specimens of Azygopus from New Zealand waters, these were not the first representatives of this genus collected from this region.

  • Complete Mitochondrial Genome Sequences of Three Rhombosoleid
    Wang et al. Zoological Studies 2014, 53:80 http://www.zoologicalstudies.com/content/53/1/80 RESEARCH Open Access Complete mitochondrial genome sequences of three rhombosoleid fishes and comparative analyses with other flatfishes (Pleuronectiformes) Shu-Ying Wang, Wei Shi, Xian-Guang Miao and Xiao-Yu Kong* Abstract Background: Peltorhamphus novaezeelandiae, Colistium nudipinnis, and Pelotretis flavilatus belong to the family Rhombosoleidae of Pleuronectiformes. Their high phenotypic similarity has provoked great differences in the number and nomenclature of the taxa that depend primarily on morphological features. These facts have made it necessary to develop molecular markers for taxonomy and phylogenetic studies. In this study, the complete mitogenomes (mtDNA) of the three rhombosoleid fishes were determined for the comparative studies and potential development of molecular markers in the future. Results: The lengths of the complete mitogenome of the three flatfishes are 16,889, 16,588, and 16,937 bp in the order mentioned above. The difference of lengths mainly results from the presence of tandem repeats at the 3′-end with variations of motif length and copy number in the control regions (CR). The gene content and arrangement is identical to that of the typical teleostean mtDNA. Two large intergenic spacers of 28 and 18 bp were found in P. flavilatus mtDNA. The genes are highly conserved except for the sizes of ND1 (which is 28 bp shorter than the two others), ND5 (13 bp longer), and tRNAGlu (5 bp longer) in P. flavilatus mtDNA. The symbolic structures of the CRs are observed as in other fishes, including ETAS, CSB-F, E, D, C, B, A, G-BOX, pyrimidine tract, and CSB2, 3.

Abstract The tree of life of fishes is in a state of flux because we still lack a comprehensive phylogeny that includes all major groups. The situation is most critical for a large clade of spiny-finned fishes, traditionally referred to as percomorphs, whose uncertain relationships have plagued ichthyologists for over a century.

Cons. int. Explor. Mer, 191: 400-408. Pressure variations from 0.5 to 50% of the reference pressure (0-1500 mb) were applied in total darkness suddenly or in cycles varying in period from 4 sec to more than 12 h. In juveniles, swimming activity and the amount of upward swimming increased during pressure decreases (sudden or progressive), during cyclic pressure variations simulating tide effects, and also during cyclic variations of low amplitude and very short period simulating wave effects in shallow areas. Larvae and juveniles reacted in the opposite sense from juveniles when they were subjected to sudden pressure variations, but reacted in the same sense when they were subjected to cyclic variations simulating waves.

Email: [email protected] urn:lsid:zoobank.org:author:55EA63EE-63FD-49E6-A216-A6D2BEB91B82 Abstract. The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Particularly, the family names are very important, because they are among the most widely used of all technical animal names. A uniform name and spelling are essential for the location of information. To facilitate this, a list of family- group names for fossil fi shes has been compiled. I use the concept ‘Fishes’ in the usual sense, i.e., starting with the Agnatha up to the †Osteolepidiformes. All the family-group names proposed for fossil fi shes found to date are listed, together with their author(s) and year of publication. The main goal of the list is to contribute to the usage of the correct family-group names for fossil fi shes with a uniform spelling and to list the author(s) and date of those names. No valid family-group name description could be located for the following family-group names currently in usage: †Brindabellaspidae, †Diabolepididae, †Dorsetichthyidae, †Erichalcidae, †Holodipteridae, †Kentuckiidae, †Lepidaspididae, †Loganelliidae and †Pituriaspididae.

  • Population Connectivity of Peltorhamphus Novaezeelandiae Between the Neighbouring Otago and Southland Regions of New Zealand
    Population connectivity of Peltorhamphus novaezeelandiae between the neighbouring Otago and Southland regions of New Zealand. Patricia Mary Mockett A thesis submitted for the degree of Master of Science at the University of Otago, Dunedin, New Zealand. July 2013 ii Abstract Connectivity among subpopulations of organisms is a primary focus in marine ecology and this knowledge is particularly imperative to the development of regulations in the management of fisheries (Cowen et al., 2007). The structure of local populations can be identified using intrinsic markers such as morphological and life history characteristics, as well as genetic markers (Bailey, 1997, Begg and Waldman, 1999). Genetic techniques are limited in that they cannot detect low levels of exchange (Thresher, 1999). Life history, morphological and meristic characteristics have been regularly employed to identify differentiation between local populations and in order to create a robust study it is reccomended that a combination of traits be examined (Begg and Waldman, 1999). The objective of the present study is to determine the level of connectivity among subpopulations of the flatfish species Peltorhamphus novaezeelandiae in the neighbouring Otago and Southland regions of New Zealand. I endeavoured to determine whether these fish form a single panmictic population over this geographical landscape or, are in fact segregated into discrete sub- populations. Flatfish as a group are an important component in New Zealand’s annual commercial catch particularly in the Otago and Southland regions, yet there is little biological information available on each species including Peltorhamphus novaezeelandiae. Fish from each region were sampled by otter trawl and morphological, stable isotope, stomach content and age determination analyses were conducted.
